Hey @shlok.sharma3, in this program we use the re module which stands for regex module. So this is usually used to find similar patterns as specified by the re.findall() method. So in this case, we give a pattern as '[0-9]+'. This regular pattern means that all the numbers from 0 to 9 (and + indicates one or more occurrences of numbers between 0 and 9) will be selected from the input string x.
Hence when we run the above program we get the following output :

['2', '29', '42']
